GENERAL: For sealing spaces in cleanrooms not occupied by FFUs, Ceiling Filter Modules or light fixtures. The assembled weight of the panels shall be sufficient to maintain 90% compression of 3/8” wide by ¼” thick urethane foam gasket applied to the mating surface of the supporting T-Grid. This compression shall be maintained against a room static pressure of up to 0.05” w.g. without the use of supplementary hold-down devices. Panel complies with ASTM E 1264 standards. If panels are to be cut, raw edges should be sealed with a recommended sealant such as Benjamin Moore Latex Primer #21600.
COMPOSITION: Vinyl clad sealed to fire retardant paper clad Gypsum on one side. Edges factory sealed. Vinyl side of the panel can easily be cleaned with damp sponge.
WEIGHT: 15 pounds
